The small yellow star ( Gagea minima ), also known as the dwarf yellow star , is a member of the lily family (Liliaceae) that is very rare in Central Europe .

Appearance

The perennial herbaceous plant reaches a height of 7 to 15 cm. Gagea minima differs from other yellow star species, among other things, by the gradually tapering tepals . The whole plant looks delicate and slim. It has two bulbs of different sizes surrounded by a common skin . From it grows a single, 1 to 2 mm wide, basal leaf , which is flat or slightly rutted and light green in color, it has no "hood tip". At the bottom it is often reddish and reaches a length of up to 16 cm. The youth leaves of non-flowering plants are shaped like a stem and neither angular nor grooved. The upper stem leaves are small and linear in shape. Only the bottom is larger, sheath-shaped, lanceolate and up to 8 mm wide.

The inflorescence is one to seven flowers . The long-stalked flowers arise from two leaf-like bracts. The narrow tepals are linear-lanceolate in shape, pointed, about 10 to 15 mm long and colored yellow. They often curve downwards. The flower stalks are glabrous or sparsely hairy.

The little yellow star blooms mainly in the months of March to May.

The number of chromosomes is 2n = 24.

Location claims, distribution and endangerment

Gagea minima grows in mixed deciduous forests and bushes. It prefers fresh, nutrient-rich and loamy soils and is considered a class character species of the beech and deciduous oak forests of Europe (Querco-Fagetea).

The small yellow star occurs from Scandinavia through Central Europe to South and Southeast Europe. It can also be found in Asia Minor as far as the Caucasus. It is a Eurasian-continental floral element.

In Germany, the species is very rarely found in the north-eastern and central areas. In Austria the little yellow star is rare and endangered in places, while in Switzerland it is seldom found in the northern limestone chains.
